' Patented May 31 1932 UNITED STATES PATENT OFFICE HERBERT PLAT'I, OF CUMBERLAND, MARYLAND, ASSIGNOR T0 OELANESE CORPORA- TION OF AMERICA, A CORPORATION OF DELAWARE TEXTILE MATERIAL AND METHOD OF MAKING SAME Ho Drawing.

This invention relates to the sizing of yarn containing organic derivatives of cellulose and relates more particularly to the providing of a size that is easily removable and which does not impart color to the yarn.

An object of my invention is to size yarn containing organic derivatives of cellulose with a size that imparts little or no color thereto. Another object of my invention is to provide a size that can be removed from the fabric that is constructed of the yarn that has been sized therewith, without the use of liquid or other wet treatments. Other objects of my invention will appear from the following detailed description.

In the weaving of fabric containing yarns of organic derivatives of cellulose, it is essential to size the yarn that comprises the warp in order to impart the strength necessary to withstand the drastic weaving operations. In the construction of certain fabrics'such as ribbons or taffeta, it is desirable to employ a size that can be removed by a dry process such as friction, crushing 'or shaking. I have found that if a size containing a drying oil whichhas been bleached or decolorized is applied to yarn containing organic derivatives of cellulose, substantially no discoloration of the yarn is produced and the size is readily removable.

In accordance with my invention I size yarn containing organic derivatives of cellulose by applying thereto a sizing composition containinga substantially colorless drying oil. The yarn to be sized may be dyed or undyed and the size may be applied thereto in any suitable manner. After the application of the size the yarn may be woven into fabric of desired construction.

Yarn containing filaments of any suitable organic derivatives of cellulose, such as organic esters of cellulose and cellulose ethers may be sized. Examples of organic esters of cellulose are cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate while examples of cellulose ethers are ethyl cellulose, methyl cellulose and benzyl cellulose. The yarn need not consist wholly of filaments of organic derivatives of cellu lose but may be a mixed yarn containing Application med November 15, 1929. Serial No. 407,570.

fibres of the derivatives of cellulose and fibres of other material such as silk,.cotton, wool or reconstituted cellulose. As stated, the size that is applied contain a substantially colorless drying oil.

Any

suitable drying oil may be employed but we yarn is preferably thoroughly scoured before the application of the size. The sizing of dyed yarn in accordance with our invention is particularly advantageous since after the fabric is constructed of the sized yarn, the size may be broken away and the fabric presented in the form in which it can immediately be sold without any further treatments.

The size may be applied to the yarn in any suitable manner. Thus the yarn may be immersed in a bath of the size in the form of a hank or other suitable package. The size may be applied by means of a wick or a roller to the yarn whileit is in transit to a packaging device, either from the machine in which it is formed or from another pack .age. In another form of the invention, the yarn in the form of a warpmay have the.

size applied thereto by means of a slasher.

After the yarn has been sized and the size permitted to dry, it may be employed as a warp in the weaving of fabric. The use of this invention in connection with the making of ribbon or other narrow fabrics is particularly advantageous since such ribbon may containing:

. Grams g per litre Potassium oleate soap 7 6 Bleached linseed oil 18 In making the, sizing bath the soap is dissolved in water at 40 C., the linseed oil then added and then enough water at 40 C'. is added to make" the required Volume. The

20 hanks of cellulose acetate yarn are worl-:ed continuously for four minutes in the bathat 40 (3., taken out, wrung gently, extracted for to minutes and dried under tension for two days at 50 to 60 C. The sized yarn is then employed as a warp in the making of ribbon or other narrow fabric and the ribbons thus formed are finished by breaking the size mechanically and without a wet finishing process.

It is to be understood that theforegoing detailed description is given merely by way of illustration and that many Variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I claim and desire to secure by Letters Patent is: i

1. In the method of making textile material, the step of applying to yarn containing organic derivatives of cellulose a size containing a bleached dryin oil.

2. In the method of making textile material, the step of applying to yarn containing cellulose acetate a size containing 'a bleached drying oil.

- 3. In the method of making textile material, the step of applying to yarn containingorganic derivatives of cellulose a size containing a bleached linseed oil.

4. In the method of'making'textile material, the step of applying to yarn containing cellulose acetate a size containing a bleached linseed oil.

5. The method of making fabric comprising sizing yarn containing organic derivatives of cellulose with a composition containing a bleached drying oil and a soap,

weaving such sized yarn as a warp into a fabric and removing the size by mechanical means.

6. The method of making fabric comprising sizing yarn containing cellulose acetate with a composition containing a bleached drying oil and .a soap, weaving such sized yarn as a warp into a fabric and removing the size by mechanical means.

7 The method of making fabric comprising sizing yarn containing organic derivatives of cellulose with a composition contain mg a bleached linseed 011 and a soap, weaving such sized yarn as a warp 1nto a fabric and removing the size by mechanical means.

12.. Fabric containing yarns of organic derivatives of cellulose sized with a composition containing bleached linseed oil.

13. Fabric containing yarns of cellulose acetate sized with a composition containing bleached linseed oil.

14. In the method of making textile materials, the steps of sizing yarn containing organic derivative of cellulose with a suspension of bleached linseed oil in an aqueous soap solution, and then subjecting the yarn while having the size thereon to a textile operation.

15. In themethod of making textile materials, the steps of sizing yarn containing cellulose acetate with a suspension of bleached linseed oil in an aqueous soap solution, and then subjecting the yarn while having the size thereon to a textile. operation.

In testimony whereof, I have hereunto subscribed my name.
